Perry added that both she and her husband plan to be more private about the details of their personal lives now that they have wed.

The star explained: "I made a promise to [him] and he made a promise to me and we have to keep that promise. That's one of the things that we keep private - our relationship. We've just kind of taken a step back because we put so much of ourselves out there professionally."

A source close to the pair recently suggested that Brand and Perry will try for a baby within the next year.
